jbpm-designer's bug, mappedName should be changed to mapped-

[luckyxb]

as in jpdl-3.0.xsd, variable's attribute name is mapped-name. But in jbpm-designer is mappedName.

<xs:attribute name="mapped-name" type="xs:string" use="optional">
 <xs:annotation>
 <xs:documentation>Defaults to the process variable name as given by the name attribute.</xs:documentation>
 </xs:annotation>
</xs:attribute>

<controller>
 <variable name="a" access="read" mappedName="a"></variable>
 </controller>
